STENCIL-STAMP.

Specication of Letters Patent.

Patented June i9, 19t?.

Application filed September 8, 1915. Serial No. l31.2),431.

To all whom it may concern.'

Be it known that I, DAVID EDGAR RICE, residing at Brooklyn, in thecounty of Kings and State of N ew York, have invented certain new anduseful Improvements in Stencil-Stamps, of which the following is aspeciiication.

This invention relates to a stencil stamp.

The object ofthe invention is to provide means whereby the subjectmatter or characters to be impressed by the stamp may be alteredindefinitely at will.

A more detailed object is to provide a hand stamp comprising an ink padanda stencil membercarried thereby, the stencil member being detachableand interchangeable with other like stencil members, the idea being thatstencil members having diii'erent characters or subject matter formedtherein may be applied for coperative use with the pad at will.

A. further object isto provide a simple, efficient and practical meanswhereby the stencil members are rendered readily attachable anddetachable.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention; and

Athe scope of protection contemplated will be indicated in the appendedclaims.

In the accompanying drawings which are to be taken as a part of thisspecification, and in which l have shown a merely preferred forni ofembodiment of the inven-v tion:

Figure l is a perspective view of a stencil stampconstructed inaccordance with this invention, the device being shown inverted.

Fig. 2 is a transverse, vertical central sectional View through thedevice shown in Fig. 1, the same being shown in upright or operatingposition.

Fig. 3 is an enlarged detail sectional view of the stencil memberdetached.

Fig. l is a perspective view illustrating a modified means of retainingthe stencil member in position.

Fig. 5 is a plan view illustrating a further modification ot' the meansfor retainy ing the stencil member in position.

lFig. G 1s a perspective view illustrating a further modification.

Fig. 7 illustrates a modified form of ink suitable handle l, by means ofwhich the stamp may be readily manipulated. rlihe pad G is held in placepreferably by having its opposite longitudinal edges turned laterallyupon the opposite sides of the body and being received in suitabledepressions, as 2,'

formed to receive them. A pair of plates 3, preferably of metal, isfixed to opposite sides of the body so as to overlie the turned portionsof the pad and retain the same against displacement.

The stencil member may be formed in any manner, but preferably comprisesa rectangular frame ll, over which a sheet of stencil paper Hisstretched. The insidel dimensions of the frame 4l are suoli as tocoincide substantially, with the outside dimensions or the pad G. V llheedges'as 5, of the plates 3, are turnedslightly outwardly so as to gripfirmly against the inner edges of the frame along at least two sides,substantially as indicated particularly in Fig. 2 of the drawings. 'lhisengagement is sutlicient to retain the frame against displacement withthe stencil paper in close contact with the surface of the ink pad. htthe same time the frame may be readily detached at will.

The structure shown in Fig. a is substantially the same as that shown inthe preceding gures, except that in this instance the plates 3 areprovided with lateral extensions 6, having turned edges 7 for engagingthe outer edge of the frame il. Portions of the extensions 6 are cutaway, as at 8, for facilitating handling of the frame.

The structure shown in Fig. 5 is the same as that shown in Fig. a,except that in Fig.

5 one of the extensions 6 is separately formed and pivotally mounted atone end, asat 9, so as to be easily swung into and out of position forgripping the edge of the frame. Obviously both of the extensions 6 maybe thus connected, if desired, but it is believed that one issuiiicient. In this fi ure the separately formed piece is indicate bythe reference character 10, and is shown by full lines, partly insection, in position to hold the frame, and by dotted lines as 10, inposition free of the frame.

In the modification Fig. 6, the frame is entirely omitted and the edgeportions, as 11, of the stencil paper 12 are turned downwardly upon theside surfaces of the stamp and held in such position 'by a separatelyformed band 13, which is readily movable into and out of clampingposition, itbeing slidably supported upon the side walls of the stamp.

The ink pad in all instances may be made of a single sheet of felt,flannel, or other suitable material, but it is preferably provided withreinforcing strips 15 as shown in Figs. 7 and 8. These strips are fixedto the longitudinal edges of the material of the pad, preferably bybeing punched into the material from opposite sides, as at 16, thestrips being U-shaped in cross section, and the edge of the material ofthe pad being received between. the legs of the strip. By this means thepad maybe readily handled and inserted or removed from connection 1 withthe body portion of the stamp when desired.

rl`he portions of the plates 3, which overlie the depressions 2 and bearagainst the turned portions ofthe pad, are resilient so as to pressyieldingly upon the pad.

Where the strips 15 are employed the same ,are received within thedepressions 2 and receive the pressure from the plates 3. In order torender the grip of the plates more effective, the walls of thedepressions 2 may be inclined, as shown in Fig. 2, if desired, or theportions of the plates overlying tlie depressions may be inclined, as

shown in Fig. 8, or both the overl ing portions of the plates and thewall o the depression may be inclined if desired. In cases where thestrips 15 are employed, said strips are preferably shaped so as to be ofgreater width at their inner edges than at theirouter edges, asindicated in Fig. 8. Also the punched portions 16 inthe strips may serveas relative shoulder portions to improve the grip of the plates 3.

1t will, of course, be understood that the stencil paper H is adapted tobe perforated or otherwise operated .upon in any manner well known inthe art for permitting passage of ink from the ink pad through portionsof the paper when the stamp is-pressed against a surface upon which itis desired to apply an impression from the stencil. The stencil papermay be operated upon in an ordinary typewriting machine for thispurpose, prior to being attached in position upbn the ink pad.

In use the plates 3 cooperate with the side walls of the depressions 2,so as to constitute recesses or pockets, each having a resilient wallportion by means of which the edges' of the ink pad are resilientlyretained. 75

In Fig. 5 the reference numerals 14 indicate small apertures throughwhich a pointed instrument may be inserted to force the stencil memberoutward, if desired.

As shown in the drawings, the face of the body portion of the stamp maybe formed on a curve so that in operation the impression may be madeupon the surface to be printed upon with a rocking motion of the stamp.This operates to effectively 35 force ink from the pad through thestencil and insures an even distribution of ink through the printingcharacters.

' As many changes could be made in this construction without departingfrom the scope of the following claims, .it is intended that all mattercontained in the' above description or shown in the accompanying drawingshall be interpreted as illustrative only and not in a limiting sense.
